Don't worry about the actual reading from the meter. They are 100 Oahm Solenoids. The fact they read not 100 is just the magnet, the coiling, etc. 100 Ohm is the designed spec.

But those resistors, perfect, They are wire wound resistors, just like solenoids, save its a resistor. They are not tiny so you can work with them easy, they are sturdy and work over a large temp range, ideal for under the hood. As beenthere pointed out, make sure they are waterproof, as wire wound, if they short it will cook. Mayby find a putty epoxy which can handle high temp. I've seen this quick setting epoxy putty at home depot. Just mash, mix, place and its hard as steel in about 20-30 minutes.

With the ohm meter, you will see ranges done with whole numbers, it will be something like 2, 20, 200, 2k, 20k, 200k or something similar. If you are on say 20k, or 200k setting and you see 2.1 that means you have 2.1k ohms. If you have the setting on 20 or 200 and you see 2.1, it means you have 2.1 ohms, not 2.1k. if you set it on a number and you see 1____ (bunch of spaces) or something odd, it means the resistance is higher than your setting and move your setting up a notch. Got it?

Yeah, I went to the web site and looked at them before from the link. Seen them before in the store, been in Radio Shacks a fair bit when I need a quick part.

No polarity in a resistor. Just connect the each end of the resistor to a lead in the femal harness on the body. Doesn't matter which direction. Just bridge the female connector with the resistor. If you can find a male connector for the solenoid, you maybe can solder the wire leads from the resistor into the pins and just plug it in. Will make for easy switching if you need it.

You can cover the entire resistor. Since its a 10 watt resistor it won't heat up that much due to the low voltage. Assuming the solenoid runs off of a 12v supply and at 100 ohms, thats only 1.44 Watts.

do i have to worry about finding which female side/pinout is the ground......do i even need to worry about a ground?

and can i just connect them wire or quick taps,or do i need to solder them?

resistors have no polarity so you can connect it in any direction. Doesn't matter which side is ground to a resistor, all it does is resist current flow.

Connect how ever u want, just make sure how ever you connect it up it won't vibrate off while driving.

Your just doing a swap-a-roo, like Indiana Jones. Tried to put a rock the same weight as the gold statue, you doing no different.

All you are doing is faking out the circuit, nothing complicated about it. Electrical Engineering is a 'black box' engineering type. You DON'T CARE what is in the box, just what the boxes specs are. If 2 black boxes specs are very similar, then to the circuit they are connected to, they will be nearly the same EVEN IF THE BLACK BOXES ARE TOTALLY DIFFERENT INSIDE.

This is what your doing. All the car knows is that it gives juice to a load thats about 100 ohms, it just happened to be a solenoid. You put a 100 ohm resistor and to the car, it sees nearly the same thing. Makes no difference they are not the same parts.

You put a 135 ohm resistor in the place of a 100 watt light bulb and to the lamp, nothing has changed. Its giving juice to something at about 130 ohms and pushing out 100 watts.

If it looks like a duck, sounds like a duck, you can use it replace any other similar duck.

it will change slightly due to the magnetic field which gets generated when it first switches openor closed, but once it been open or closed for a period of time, it will stabilize and return to it typical values.

Only when there is a change (i.e. when its turned from off to on, or on to off) will a solenoid appear different than a resistor but at soon as the magnetic field has been generated or discharges from the coils and isn't changing any more, its just a resistive load.

Basically, resistors don't do anything special. They act the same at all time, they resist. Solenoids (a form of inductor) react when there is a change in the circuit. If nothing is changing its almost like the inductor isn't even there, just its resistance in the windings of wire, i.e. the 91 ohms you measured, but as soon as you flip the switch, the inductor continues to try to do what it was just doing, due to the magnetic field or lack there of and resists the change. Kinda like a pipe of water. You turn the faucet off but the water keeps going.. Could also think of it like a siphon. the inductor's (solenoids) magnetic field continues to make the current flow even when you turn it off until it runs out of magnetic field.

Nothing you need to worry about with this in any way, shape, or form. Just FYI.
